Installing an EV charger at a detached home starts with checking the electrical installation, not choosing a model. The right charging power depends on your vehicle, the home’s supply and when you can charge. Use this checklist to prepare for an installer’s visit and compare quotes.

1. Check what your car can accept

Look up the vehicle’s maximum AC charging power and connector in its manual or manufacturer specifications. A more powerful charger will not make the car charge faster if the vehicle cannot use that power. Consider your daily driving and how long the car is usually parked: these details help size the setup around real use rather than oversizing by default.

2. Review the supply and distribution board

The installer should assess the distribution board, available capacity, the circuit route to the parking space and household loads that may run at the same time. Ask whether the charger should be power-limited or use dynamic load management to adapt charging to other consumption. The answer depends on the installation and your habits; there is no single right power level for every home.

3. Plan the location and cable route

Show where you park and where the unit could go. Cable distance and route, wall penetrations, exposure to weather and access to the meter can affect the work and price. Ask the quote to spell out materials, the proposed route, any building work and assumptions that still need checking.

4. Coordinate charging with solar panels

If you have or are planning solar panels, ask whether the charger can modulate its power and what equipment or configuration is needed to follow generation. Explain whether you want to prioritise solar surplus, charge at a set time or combine both. Compatibility depends on the equipment and how it is connected.

5. Ask for a documented installation

The charging installation must be designed to meet applicable electrical rules, including Spain’s ITC-BT-52. Request the model and functions, planned protective devices, scope, total price and applicable commissioning records in writing. The installer must verify the specific case; do not make electrical connections or alter the distribution board yourself.

Compare quotes on the same basis

  • Proposed power and how it matches your vehicle and supply.
  • Cable length and route, protection and any additional work.
  • Dynamic load management, app control and solar integration, if included.
  • Warranty, documentation, timeline and final price including taxes.
